This invention relates to shoe-supports, and is illustrated as embodied in a jack'designed to be employed in a machine for-attaching heels by nails driven from the in- It is difficult, with the somewhat convex metal tops of jacks often employed in the at tachment of heels from the insides of shoes, to secure proper distribution of the workclamping pressure over the heel-seat portion of a shoe, so that the heel-seat on the sole shall be properly forced into contact with the cupped end of a heel and the various nails or other fastenings fully driven, and at the same time to avoid so localizing the pressure upon the margin or other portion of the seat of a heel of Wood or similar material that said heel shall not be broken. It is an object of the present invention to guard against this difficulty.

In the attainment of this object, as a feature of my invention, there is provided a shoe-support having tubes for receiving nails or other fastenings, about which tubes is a body arranged for contact with the heel-seat portion of a shoe, said body and tubes being organized for relative movement under pressure of the work and offering to the shoe, when under the influence of such pressure, substantial uniformity of contact and reaction over the entire area. This body is preferably capable of conforming to the contour of the heel-seat portion, being of such yieldable material as rubben Because of the capacity of the contacting body for adapting itself to the opposing surface of the work,

the stresses set up in the heels being attached I are equalized and their fracture is avoided. As illustrated, the contact-surface of the yieldable material lies outside the ends of the nail-tubes. This permits the body, under the working pressure, to occupy a surface substantially identical with that in which the ends of the tubes are situated, thus giving more complete continuity of engagement with the work.

This and other features and the various objects of the invention will be made appar- -5u ent in the following description of a particu- I SHOE surro'n'r 55321, and new Britain October 6, 1924;

the accompanying drawing, in which Y Fig. 1 is apartial side elevation of said support taken on the line 1-1 of Fig. 2; and

Fig.2 is a top plan view of the support.

At; 10 appears the body-portion of my imlar form of improved support shown in proved jack or shoe-support, in which is a series of vertical openings 12, here shown as five in number, arranged in accordance with the nailingdesign which it is desired to-employ. Seated in counterbor'ed upper ends of the openings are nail-tubes 18, shownas in twovertical sections, they being thus divided to enable them more readily to be formed to receive nails of such a type as those known as shovel-headed. Each pair of tube sections is surrounded by a'sleev'e 14 retaining'the two portions assembled, this sleeve having at its lower end aflange 16 resting upon the top of the body-portion 10. The sleeves pass" through openings in a retaining plate 18,

overhanging the flanges 16 and held in place upon'the jack by one or more screws 20. In the tubes operate drivers 22 carried by a head 24, formed uponthe upper extremity of a' spindle 26 arranged to reciprocate in a vertical passage through the jack. The spindle maybe actuated in any convenient manner, the driving means not being shown. Carried within a recess in the upper portion of the jack andcontacting at its lower end with the head 24c'is a spring 28 acting to hold the drivers normally depressed.

Covering the top of the jack, overlying the platel8 and surrounding the tubes 13 is a "body ofyieldable material, which may be furnished by a pad 30 of rubber. The pad is shown as practically continuous, being broken only by openings 82 which the nailtubes fit closely. It is somewhatthi'cker than the length'of thetubes above the plate 18.

The'. general contour ofthe upper surface ofthe pad, or that with which the heel-seat portion of a shoe operated upon contacts, ap-

proximates that of such heel-seat portion,

resembling in this respect the usual metal jack-top.-- I

engaging the heel-seat, pressure is applied to the work, as is customary, to hold the heel This is to prepare it to receive the inserting force of the nails which have been placed in the tubes 13.and are carried upon the ends of the drivers. The

nails are driven by the elevation of the spindle 26 when the machine in which the jack is used is started. The clamping pres sure necessary to prevent displacement of the heel is considerable, and if a jack-top o1 non-compressible material, as iron, is employed, the lack of identity between the contours of the contact-surface of the jack and the varying forms of the cupped ends of woodor other frangible heels which are to be nailed throws unevenly distributed stresses.
